It does seem like hordes of leftist-minded folk really are running on some sort of non-thinking predictable algorithm, just getting triggered and spewing out the programmed response given to them by their TV sets without thinking about them. I know a few/have some facebook contacts, its eerily similar to this described pattern the way they react with 100% consistently to the latest MSM 'news of the day'.

I know this next part may be taking it too far beyond the intended usage of the meme, but I found this line from Penxv's 1st link an interesting (albeit far-fetched) theory:

“I have a theory that there are only a fixed quantity of souls on planet Earth that cycle continuously through reincarnation,” a 4Chan poster wrote. “However, since the human growth rate is so severe, the soulless extra walking flesh piles around us are NPC’s [sic], or ultimate normalfags, who autonomously follow group think and social trends in order to appear convincingly human.” NPCs aren’t even worthy of a classic wake up, sheeple. They can’t!"

- freaky!!!

I don't ascribe to that philosophy but it does appear to be the post that set off the meme.
